Surprisingly YouTube still don’t have a way to easily embed only your latest YouTube video onto your site so that every time you upload a new video it automatically updates on your site. WordPress users can download a plugin which allows this but Blogger users have the option of two gadgets (listed below), although neither have many options for customising. This tutorial will show you how to embed your latest video from YouTube to Blogger so it automatically updates.
1. USING BLOGGERS GADGETS
Add videos as a text list
Go to Layout > Add new gadget > Feed and enter your channel URL – http://youtube.com/user/YOUR-USERNAME. Select from the options and save.
Add videos as an image list
Go to Layout > Add new gadget > Video Bar and enter your username next to channel. Remove text from the other fields and save.
2. EMBED LATEST YOUTUBE VIDEO IN SIDEBAR ON BLOGGER
This method embeds your latest video, just like if you embedded one particular video but it will update each time you upload a new video.
<iframe width="300" height="200" src="http://www.youtube.com/embed?max-results=1&controls=0&showinfo=0&rel=0&listType=user_uploads&list=USERNAME" frameborder="0" allowfullscreen></iframe>
Alter the width and height to suit your design. Change USERNAME to your YouTube username and save. When you go onto your blog, your latest YouTube video should be showing.
